Recently, due to the complexity of the vehicle and various driving patterns, the driver has to operate more devices while driving, demands more information from inside and outside the vehicle, and the types of information are very diverse such as voice, data, video, and graphics. There is a trend.

In order to meet the needs of the driver, the AVN (Audio Video Navigation) system mounted on the vehicle provides the driver with useful information for driving in conjunction with a driver information system (DIS), a navigation system, and a telematics system. In addition, the AVN system includes a HMI (Human Machine Interface) for receiving letters (Korean, English, etc.), numbers, and special characters from the driver.

1 is an exemplary view of an HMI of a conventional AVN system.

As shown in Fig. 1, the HMI of the conventional AVN system has a dial key 11 that rotates in a clockwise / counterclockwise direction so that a user can position a cursor on a desired letter, number, or special character. Include. Such a dial key 11 can be pressed (exactly pressed down), and when a pressing operation is performed by the user, a letter, number or special character at which the cursor is currently positioned is selected.

In addition, the HMI includes various selection buttons such as an FM / AM selection button, a DMB selection button, a disk / AUX selection button, a telephone selection button, and a mogen button.

Hereinafter, a method of inputting information through the HMI will be described with reference to FIG. 2.

2 is an exemplary view of an information input screen in a conventional AVN system, where (a) shows a Korean input screen and (b) shows an English input screen.

As shown in (a), the Korean input screen displays all consonants and vowels constituting the characters in a line in track form. The consonants are displayed in clockwise order and the vowels are displayed in counterclockwise order.

As shown in (b), the English input screen displays all alphabets in order in the clockwise direction.

Accordingly, the user selects a character to be input by turning the dial key 11 clockwise / counterclockwise while displaying a desired character input screen. For example, as shown in (a), when the dial key 11 is rotated clockwise by a certain amount while the cursor is located at 'a', the input processing device (not shown in the drawing) of the AVN system is positioned at 'a'. While changing the 'b' to the 'b' in the center of the screen changes to 'b'. At this time, when the user presses the dial key 11, 'b' is selected.
